Ping-Tung Chang, a math professor at Matanuska-Susitna College in Palmer, Alaska, is one of four 2010 U.S. professors of the year honored by the Council for Advancement and Support of Education, which is sponsored by the Carnegie Foundation for the Advancement of Teaching.
Chang is constantly exploring new ways to help his students learn mathematics in the classroom. Saying the “teacher talks, students listen” model of learning is ineffective, Chang leads an interactive classroom where students debate and discuss different methods to solve problems. This hands-on, problem-solving approach helps students become more confident and engaged in solving and reasoning. Chang also believes in using tests for formative assessment instead of grading. Students are encouraged to retake tests until they master the content, a strategy that has led to a boost in student confidence and a more relaxed learning environment. And for nearly 25 years, Chang has provided refreshments for students, reinforcing his belief that students are unable to learn if their basic needs are not met. Chang also volunteers to help high school students struggling with math and has worked extensively in China to develop more effective mathematics teaching methods.
Chang was the national winner in the community college category. Professors also were honored for exemplary teaching at the state level.
